Abstract
The utility model discloses a massage pool circuit board protection structure, comprising an electric appliance box, a circuit board provided with a plurality of electric appliance elements on a surface thereof, and an insulating embedding material; wherein the circuit board is placed in the electric appliance box, the insulating embedding material can be embedded between a lower surface of the circuit board and the electric appliance box and an upper surface of the circuit board, the insulating embedding material can cover all solder joints on the circuit board. According to the massage pool circuit board protection structure of the utility model, by embedding an insulating material, especially an epoxy resin insulating embedding material having an excellent insulating characteristic, between the electric appliance box and the circuit board and the upper surface of the circuit board, the massage pool circuit board used in an extremely wet environment has better waterproof, moistureproof, heatproof and insulating capabilities, and a service life of the circuit board is greatly prolonged.
Description
Technical field
The utility model relates to a kind of protective structure for circuit board, specifically relates to a kind of massaging pool protective structure for circuit board.
Background technology
The environment for use of massaging pool is relatively moister, the circuit board of traditional massaging pool does not have insulating barrier, perhaps surface coverage has the insulating varnish of thin layer, relatively poor phenomenons of ubiquity waterproof, protection against the tide and insulating capacity all, easily cause the problems such as short circuit, electric leakage and solder joint corrosion, the solder joint corrosion causes that further the temperature rise increase causes circuit board to burn, and has shortened useful life.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of massaging pool protective structure for circuit board, has better waterproof, protection against the tide, heat-resisting and insulating capacity, the circuit board multiple advantage such as be increased dramatically useful life.
The technical solution of the utility model is achieved in that
A kind of massaging pool protective structure for circuit board, comprise that electrical appliance kit, surface be equipped with circuit board and the insulating encapsulating material of several electric elements, described circuit board is positioned in the described electrical appliance kit, described insulating encapsulating material can be potted between described circuit board lower surface and the described electrical appliance kit and the upper surface of circuit board, and described insulating encapsulating material can cover all solder joints on the described circuit board.
As further improvement of the utility model, described insulating encapsulating material is a kind of in epoxide resin type insulating encapsulating material and the polyurethane-type insulating encapsulating material.
The beneficial effects of the utility model are: by between electrical appliance kit and circuit board and circuit board upper surface embedding insulating properties material, the epoxy resins insulation Embedding Material that particularly has the superior isolation characteristic, can make the massaging pool circuit board that in very moist environment, uses have better waterproof, protection against the tide, heat-resisting and insulating capacity, is increased dramatically the useful life of circuit board.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model perspective view.
By reference to the accompanying drawings, make the following instructions:
1---electrical appliance kit 2---circuit board
3---insulating encapsulating material
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, but is not restricted to these embodiment.The utility model is contained any in substituting of making of its marrow, modification, equivalent method and scheme.
A kind of massaging pool protective structure for circuit board, comprise electrical appliance kit 1, circuit board 2 and the insulating encapsulating material 3 of several electric elements is equipped with on the surface, described circuit board is positioned in the described electrical appliance kit, described insulating encapsulating material can be potted between described circuit board lower surface and the described electrical appliance kit, and the upper surface of circuit board, described insulating encapsulating material can cover all solder joints on the described circuit board, like this, the thickness of insulating encapsulating material has covered all solder joints of circuit board upper surface and lower surface fully, circuit board solder joint and moist on every side environment are isolated fully, thereby play better waterproof, moistureproof, heat-resisting function, circuit board is increased dramatically useful life.
Preferably, described insulating encapsulating material is a kind of in epoxide resin type insulating encapsulating material and the polyurethane-type insulating encapsulating material, because the epoxide resin type insulating encapsulating material has that adhesiveness is good, insulation property are good, chemical proofing and low cost and other advantages, therefore, can play massaging pool circuit board waterproof, protection against the tide and the effect that improves the circuit board life-span of ensureing.
Take the epoxy resins insulation Embedding Material as example, implementation of the present utility model is as follows: the circuit board that several electric elements at first will be housed is put into electrical appliance kit, then the liquid-state epoxy resin with deployed ratio is poured onto in the electrical appliance kit, after liquid-state epoxy resin solidifies, between the lower surface of circuit board and electrical appliance kit and the upper surface of circuit board can form epoxy resin layer.
The thickness of epoxy resin layer is all solder joints of covering board upper surface and lower surface at least fully.
In the situation that ambient temperature is low, the solidification process of above-mentioned liquid-state epoxy resin can carry out in bakery or air-conditioned room, to accelerate the formation of epoxy resin layer.
